Popis: When canisters filled with radwastes are emplaced in a deep bedded salt repository the heat produced by the decaying waste will cause high temperatures and moderate thermal gradients to develop in the salt. The temperature and thermal gradient may be sufficient to cause the brine inclusions present to migrate towards the canister. The larger inclusions of SALT VAULT (1) were shown to migrate readily toward the emplacement hole while the very small ones were either unable to migrate or migrated very small distances (2). The rate of droplet migration can be limited either by ion diffusion through the liquid droplet or by the kinetics of ion removal from or deposition on the facets of the droplets. When the diffusivity and solubility of the solid in the liquid are large, the kinetic processes at the solid-liquid interface control the overall droplet velocity.
